ABSTRACT = {We study two notions of negative influence namely negative regression and negative association. We show that if a set of symmetric binary random variables are negatively regressed then they are necessarily negatively associated. The proof uses a lemma that is of independent interest and shows that every binary symmetric distribution has a variable of ``positive influence''. We also show that in general the notion of negative regression is different from that of negative association.},
